Abstract: Apparatus and methods based on signal processing techniques are disclosed for determining the distance of an object from a camera, rapid autofocusing of a camera, and obtaining focused pictures from blurred pictures produced by a camera. The apparatus of the present invention includes a camera characterized by a set of four camera parameters: position of the image detector or film inside the camera, focal length of the optical system in the camera, the size of the aperture of the camera, and the characteristics of the light filter in the camera. In the method of the present invention, at least two images of the object are recorded with different values for the set of camera parameters. The two images are converted to a standard format to obtain two normalized images. The values of the camera parameters and the normalized images are substituted into an equation obtained by equating two expressions for the focused image of the object. The two expressions for the focused image are based on a new deconvolution formula which requires computing only the derivatives of the normalized images and a set of weight parameters dependent on the camera parameters and the point spread function of the camera. In particular, the deconvolution formula does not involve any Fourier transforms and therefore the present invention has significant advantages over prior art. The equation which results from equating two expressions for the focused image of the object is solved to obtain a set of solutions for the distance of the object. A third image of the object is then recorded with new values for the set of camera parameters. The solution for distance which is consistent with the third image and the new values for the camera parameters is determined to obtain the distance of the object. Based on the distance of the object, a set of values is determined for the camera parameters for focusing the object. The camera parameters are then set equal to these values to accomplish autofocusing. After determining the distance of the object, the focused image of the object is obtained using the deconvolution formula. A generalized version of the method of determining the distance of an object can be used to determine one or more unknown camera parameters. This generalized version is also applicable to any linear shift-invariant system for system parameter estimation and signal restoration. <IMAGE>

Abstract: Disclosed is a plasma torch in which the position of the center electrode (1) is adjustable relative to the orifice of the plasma torch (2). The invention is based on a construction in which the center electrode (1) is mounted to the body part (9) of the plasma torch by way of a pivotal ball joint (7, 23), whereby the electrode (1) can be pivotally rotated in said joint (7, 23), thus making it possible to align the electrode tip to the orifice center of the plasma nozzle (2). The spherical element (7) of the pivotal joint is attached to the bearing box (23) with the help of a tightening gland nut (11, 12). The depth of the center electrode (1) can be adjusted by rotating a depth adjustment gland nut (14), which is attached to the spherical element (7) by a threaded joint. Due to its versatile adjustability, the function of the plasma torch can be maintained in a stable range, thus significantly contributing to reduced wear and damage of the plasma nozzles. <IMAGE>

Abstract: A calibrated spectrometer can indirectly determine a physical or chemical property of a sample based upon spectral responses measured by the spectrometer with respect to the particular sample. This invention is directed to a method for calibrating or recalibrating a second spectrometer in light of a first spectrometer, or itself, respectively. The calibration employs a unique selection and manipulation of spectral data obtained from both the first and the second instrument. The recalibration employs a unique selection and manipulation of spectral data from the same first instrument, that is obtained both before and after the need for recalibration arises. Instead of modifiying the respective responses of the first and second instrument, or the first instrument before and after the need for calibration arises, this invention modifies the calibration equation of the second, or recalibrated instrument, to yield consistent results to those obtained by the first instrument, or the first instrument before it goes out of calibration. A calibration equation is an equation which transforms spectral data of a particular sample at a variety of wavelengths to a calculated value for a chemical or physical property. Generally, the form of such calibration equations is that of a linear combination of absorbances or mathematical transforms of absorbances measured by the first and second instrument for each sample. Surprisingly, and confirmed statistically, the accuracy of the calibrated or recalibrated instrument is maintained and in some instances improved.

Abstract: When bit streams consisting of a number of information words are switched through in the switching networks of digital communication systems, bit corruption occurs. By correcting these bit errors, only the information word correctly switched through is forwarded to the end subscriber after the switching-through when the switching network halves are constructed in duplicate and are switched to be active in each case. The fact whether an information word has been correctly switched through is determined by means of a combined parity bit check and a bit-by-bit comparison with the information word switched through in parallel after the switching-through has taken place. It must also be ensured that bit corruption by the units (latches) involved in the switching-through process is also discovered and corrected. <IMAGE>

The open front side of the container (3) is in this case turned towards an unloading door (10) which is suspended so that it can swing in the set-up frame (2). The swing axis (14) lies outside the plane of the unloading door (10). After locking, the set-up frame (2), with the roll container (3) therein, is tilted forward. In the course of this, the container moves with the open front side, still shut off by the unloading door (10), in the direction of a discharging conveyor belt (25) lying below it. After the tilting, the unloading door (10) swings away, and in making this movement lays the parcel goods on the discharging conveyor belt (25), while moving along close to a guide wall (27) which is placed parallel to the conveyor belt (25). <IMAGE>
